This is the first book devoted to the correspondence of composer Aaron Copland, covering his life from age eight to eighty-seven. The chronologically arranged collection includes letters to many significant figures in American twentieth-century music as well as Copland's friends, family, teachers, and colleagues. Selected for readability, interest, and the light they cast upon the composer's thoughts and career, the letters are carefully annotated and each published in its entirety. Copland was a gifted and natural letter writer who revealed much more about himself in his letters than in formal writings in which he was conscious of his position as spokesman for modern music. The collected letters offer insights into his music, personality, and ideas, along with fascinating glimpses into the lives of such other well-known musicians as Leonard Bernstein, Carlos Chávez, William Schuman, and Virgil Thomson.
